Question

H n - - - n - - - n in hydrogen azide (above) the bond orders of bonds (i) and (ii) are :

Answer 1

Hey dear,

● Answer -
Bond order of both N-N bonds is 2.

● Explanation -
[Refer to the image for resonant structures of hydrogen azide.]

Bond order is calculated as -
Bond order = (Total no of bonds betn two atoms in all resonating structures) / (Total no of resonating structures)

For 1st bond (HN-N),
Bond order = (2+1+3) / 3
Bond order = 2

For 2nd bond (N-N),
Bond order = (2+3+1) / 3
Bond order = 2

Hence, bond order is 2 for both N-N bonds.


Hope this helps you.
